Abstract: An inkjet recording apparatus is adapted to form an image on a printing medium 10, and recognize an image forming region as a region of pixels having drop amounts unequal to zero in the image. A drop amount increase/decrease controller 342 executes an increase/decrease process of drop amount at a current pixel as a target of the process, in accordance with an attribute of the current pixel when the current pixel is included in the image forming region. Pixels are made of ink discharged from nozzles arrayed in a scan direction perpendicular to a transfer direction of the recording medium 10. The drop amount increase/decrease controller 342 executes the increase/decrease process of drop amount in a reverse increase/decrease pattern to ink to be discharged from a neighboring nozzle.

Abstract: An image processor includes a tone converter operable when a pixel of input image data is determined as having a value greater in color saturation than a prescribed saturation value. In this operation, the tone converter changes a threshold for each color in a dither matrix associated with the pixel to make the thresholds different in correspondence to color component values of the pixel. The tone converter generates color component values of the pixel constituting image data to be output, based on comparisons between the respective color component values and the changed thresholds.

Abstract: An input of image data is received, and information of width and/or thickness of a recording medium, which receives an image representing the image data to be recorded thereon, is received. Then, a preset pressing pressure value, which is used when the image is recorded on the recording medium, is obtained based on the information of width and/or thickness, and information of image density in the reference area, which is a part of the image data, is obtained. Then, converted image density information is obtained by converting the information of image density in the reference area based on the pressing pressure value and the information of image density, and image data is generated according to the thus obtained converted image density information.
